"OMG" is a song by American recording artist Usher and American rapper will.i.am and B.E. wrote and produced the song. It uses the auto-tune effect in several lines, as well as Jock Jams-esque sports arena chanting. It was released on March 22, 2010 as the first worldwide single off his sixth studio album, Raymond v. Raymond, and the fourth single overall, following the three US singles "Papers", "Hey Daddy (Daddy's Home)", and "Lil Freak". The song was met with a mixed reception from critics, who criticized the use of auto-tune, but commended the song's dance and club vibe. The song marks the second time that Usher has collaborated with will.i.am, following the single "What's Your Name", from his previous album Here I Stand (2008).

"OMG" topped the charts in Australia, Ireland, New Zealand, the United Kingdom and the United States. The song became his ninth number-one hit in the United States, making him the first 2010s artist to collect number-one singles in three consecutive decades. He became only the fourth artist of all-time to achieve that feat. Usher also became the third artist to have at least one number-one song from five consecutive studio albums. The song's choreography and dance-heavy accompanying music video has been compared by critics to that of "Yeah!". Usher performed the song live several times including on the ninth season of American Idol with will.i.am. He also performed the song as a part of a medley during his critically acclaimed performance at the 2010 MTV Video Music Awards. "OMG", was named the fifth best selling song of 2010 in the US, selling 3.8 million units.[2] The song sold 6.9 million copies worldwide during that year.[3]

"OMG was written and produced by The Black Eyed Peas frontman, will.i.am. The tune was recorded at Chung King Studios, New York City. Dylan "3-D" Dresdow mixed the record at Paper V.U. Studios, North Hollywood.[4] The vocal sample of a crowd shouting "owowowo" used in the song was recorded by will.i.am while performing with The Black Eyed Peas on the French TV show Taratata.[5]

"OMG" is a midtempo pop song, drawing from the subgenres of dance-pop and synthpop, and is also influenced by R&B.[6] The song also infuses hints of Eurodance.[7] Several lines feature the Auto-Tune vocal effect, and makes use of "hypnotic" hand claps, and Jock Jams-esque arena chanting.[8] The song is set in common time, and has a tempo of 130 beats per minute.[6] It is written in the key of E minor, and Usher's vocals span from the low note of G3 to high note of E5.[6] It follows the chord progression Em–D–Bm7–C6.[6] According to James Reed of the Boston Globe, Usher is featured in a staccato delivery over the song's minimalist dance beat."[9] will.i.am begins the song with the line, "Oh my gosh" then Usher starts singing the chorus. He performs his verse and the second chorus, before will.i.am gives his verse. "OMG" concludes with an extended final chorus.[6] Mikael Wood of The Los Angeles Times said that the lyrics of the song detail Usher's encounter with a woman in a club.[7]

The song has garnered mixed reception, with most critics disapproving of the auto-tuned vocals, and the production and appearance by will.i.am. Edna Gundersen of USA Today said that Usher seemed "disengaged" on the song, and allowed will.i.am. to "bludgeon" the song with auto-tune.[10]Greg Kot of the Chicago Tribune said the song was one of the tracks where production fell short on Raymond v. Raymond, calling the song another auto-tuned "formulaic chant" by will.i.am.[11]The New York Daily News said that the song is "as annoying as the tech-speak it mimics."[12] Andrew Winistorfer of Prefix Magazine preferred "Lil Freak" to be the album's big single, stating that the song "doesn't come close to matching the filthy heights of "Little Freak," [sic] but the sports arena chanting thing hasn't been done this well since the '90s when Jock Jams were enormous."[13] Winistorfer also said that Usher brought back his "bad taste" in collaborators since Lil Jon on "Yeah!", saying that having the latter on this song would be an improvement.[14]

James Reed of the Boston Globe said that Usher "fares better" on the collaboration.[9] Mikael Wood of The Los Angeles Times commended the song's "thumping" groove.[7] Gail Mitchell of Billboard said that Usher "pumps up the beat on the infectious club anthem."[15] Caroline Sullivan of The Guardian, called the track "irresistible".[16] Monica Herrera of Billboard magazine said the song, like "Yeah!", appealed to a broader audience and attuned to clubs. Herrera also said that "the lyrics are hypnotic hand claps and soccer-game chants that fade in and out to keep the party going".[8]

In 2010, WYOY disc jockeys compared part of Usher's verse to a song sung by Homer Simpson in "Dude, Where's My Ranch?", a 2003 episode of television comedy The Simpsons.[17] The cadences of the line, "Honey got a booty like pow, pow, pow. Honey got some boobies like wow, oh wow" were compared to those of Simpson's tune, "Christmas in December, wow wow wow. Give me tons of presents, now now now."[18][19] Simon Vozick-Levinson of Entertainment Weekly disagreed, calling the likenesses "a random coincidence".[20]

The song debuted at number fourteen on the Billboard Hot 100 selling 130,000 units in its first week.[21] The song became the third-highest debut on the Billboard Hot 100 of Usher's career, behind 1997's "Nice & Slow" at number nine, and 1998's "My Way" at eight.[22] For the week ending May 15, 2010, the song lifted to number one on the chart, becoming Usher's ninth number-one single and Will.i.am's first number one single as a solo artist (or without his group, The Black eyed Peas). The song collected airplay and digital gainer honors, moving fourteen to seven on the Hot 100 Airplay chart, and two to one on the Hot Digital Songs chart.[23] The song later topped both charts.[24] By March 2011, the song has reached 4 million in sales,[25] and as of May 2013, the song has sold 4,719,000 copies.[26]

With the song, Usher tied with the Bee Gees, Elton John, and Paul McCartney for ninth among artists all time with the most Hot 100 hits.[27] Usher also became the third artist, behind McCartney and Michael Jackson to collect at least one number-one single from five consecutive albums.[27] The song made Usher the first artist in the 2010s to have a number-one single in three consecutive decades, Usher's being the 1990s, 2000s and 2010s.[23] He became only the fifth artist of all time to accomplish this, the others being Stevie Wonder in the 1960s, 1970s and 1980s; Michael Jackson in the 1970s, 1980s, and 1990s; and Madonna and Janet Jackson in the 1980s, 1990s and 2000s.[23] "OMG" was the second shortest title to lead the chart, tying Jackson's "Ben", "Bad", and "ABC" with the Jackson 5, with Britney Spears' "3" being the chart-topper with the shortest title.[27]

Usher and will.i.am shot the video the weekend of March 6, 2010.[38] The video was directed by Anthony Mandler.[38] In an interview with Rap-Up, Mandler said about the concept of the video: "...The video is a spectacle. It really emphasizes what we love about Usher and the character and the icon that he is, and most importantly, it’s really a video that showcases his superstardom".[39] The video was released on March 30, 2010, on VEVO and AMTV.[40] According to Mandler, the original idea for the video was citing Max Headroom, a fictional artificial intelligence character from 1980s British television and film.[41] The reference is made when Usher is seen on a flickering television at the beginning of the video.[41] Mandler specified, commenting, "Max Headroom was always in his room," he continued, "this unidentifiable room, '80s shapes. I used that for inspiration."[41] Usher stated that he wanted to do something theatrical and fun, and that while will.i.am. brought the international sound, he wanted to bring the producer into his world, "working off of each other and playing off of each other as artists, but the cinematography would be artistic and incredible."[41] Mandler described the visuals in the clip as "Hitchcock-ian", as well as simply captuiring Usher in his element, as he said he wanted the R&B singer's talent to take over.[41] He further explained, stating,

"The concept was to create a world where we put Usher in a space where he does what I think he does better than anyone else in the world, which is perform at a level and magnitude of a superstar and take us, the viewer, whether audible or visually, on a journey, not a ride. And, in that, I wanted to create an unpredictability, so one set leads to another and another, and you never know what's gonna happen. Along the way, Usher becomes our guide. We're so focused on him, we don't notice the change. The thing is unfolding little by little, and you can't quite see far enough ahead to know what's gonna come next."[41]

A still from the video, showing the first scene with Usher on a flickering television, paying homage to Max Headroom

The video begins with Usher flickering on a television in a room, before we see him in a scene dancing with blue flashing lights, and will.i.am. is shown in a similar room with red flashing lights. Usher is then shown with female background dancers in a white room. In the scene he dons a pair of glasses which show the dancers performing through the lens. Usher then dances outside in front of a concrete wall, with male background dancers appearing as shadows. As will.i.am. performs his verse, he and Usher are seen in their corresponding rooms with flashing lights. After this, Usher puffs a cigar and dances with male background dancers in an arena-like area, whilst he is also joined by female dancers with flashing lights on the floor, with the video ending with Usher shown on the flashing television.[42]

In a review of the video, Brad Wete of Entertainment Weekly said, "For a song with such a title, it sure does take a minute for its video to build up to wow-worthy moments. After some clean dance sequences, the magic begins. Usher grooves with shadows, puffs out O’s with cigar smoke, and then links back up with his ladies on a primary colored dance floor to show off his steps."[43] Chris Ryan of MTV News compared the video's flashing lights to the music video for "Yeah!", and called the song an answer track to Trey Songz's "LOL".[44] At the 2010 MTV Video Music Awards, the clip was nominated for Best Dance Video, Best Choreography, and Best Male Video.[45]

The performance was received with critical acclaim. On Usher specifically Antai said the performance was like "liquid magic", saying, "He took it to the level that comes after the next level. The penthouse level."[54] He was aided by about a dozen background dancers, the males in skeleton-like costumets, and the females donning a one-piece, gloves and boots.[55] The "OMG" performance was accompanied by red laser lights, making an illusion as if the stage disappeared.[45] The lights spelled out "O.M.G" as well as "Usher", as dancers lowered from the ceiling.[45] Jayson Rodrgiguez of MTV News commented, "The singer moved and grooved, proving that he's the R&B star that everyone pays attention to for the big moments."[53] Rochell D. Thomas, also of the site said "Call it what you will: talent, swag, skills...When he steps on the dance floor, some mysterious thing comes out of him and puts the G in groove."[45] Thomas went on to say that Usher's dance moves would make "the late great Michael Jackson jealous" in the stage production "that included more special-effects bells and whistles than a summer blockbuster."[45] Chris Ryan of MTV Buzzworthy also compared the performance to Jackson, calling it overall, "One part "Tron," one part laser show, one part Michael Jackson choreo tribute, and all spectacle."[55] Usher appeared with The Black Eyed Peas to perform the song during the halftime show of Super Bowl XLV.
